Abstract

Background and purpose

Spontaneous intracerebral haemorrhage (ICH) is the most fatal form of stroke with the highest morbidity and disability rate of all stroke types. Recent data suggest that the genetic background has a sizeable and mostly undiscovered effect on the brain haemorrhage risk. Since the coagulation system is crucial to ICH pathology, we studied the significance of the FGA Thr312Ala polymorphism in two European populations.

Materials and methods

We genotyped 550 and 224 controls as well as 261 and 242 stroke patients in Polish and Greek populations, respectively. The ICH diagnosis was confirmed by computed tomography. The FGA Thr312Ala polymorphism was analysed using real-time polymorphism chain reaction.

Results

Both crude and multivariable regression analyses showed that the studied polymorphism is a protective factor in the Polish population under the dominant and additive models of inheritance. Those results did not replicate in the Greek population. The meta-analysis of results from the Polish and the Greek populations proved that FGA Thr312Ala polymorphism affects the risk of ICH in the dominant model of inheritance.

Conclusions

The FGA Thr312Ala polymorphism affects a risk for ICH in the Polish but not in the Greek population. An advanced meta-analysis of well-designed studies with a significant number of cases might provide useful information of novel polymorphisms, including the FGA Thr312Ala polymorphism, and their role in ICH pathology.
